摘要

An IP multimedia subsystem (IMS)-based service sharing system includes an IMS, a master IMS terminal registered in the IMS, and a slave IMS terminal not registered in the IMS, wherein the master IMS terminal transmits IMS registration information to the slave IMS terminal by using near field communication (NFC), and the slave IMS terminal is registered in the IMS on the basis of the transmitted IMS registration information.
